WATER-HAMMOCK.

Application filed September 3.7, 1917.

To all whom it may concern.

Be it known that l, Enema Unnnnwoon, a citizen of the United States,residing at Gary, in the county of Lake and State of Indiana, haveinvented a certain new and useful Improvement in \Vaterl lammocks, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to water hammocks and has for its object theprovision of a hammock structure adapted more particularly for use inthe water for pleasure purposes. In general, my invention comprises acradle or stretcher portion, the opposite ends of which are buoyed up bysuitable means so that the user may lie on the stretcher portion on topof the water.

In one form of my invention I utilize pneumatic pillows as the buoyingmeans, and my invention contemplates the provision of improved valvemechanism for these pneumatic pillows.

I will describe my invention more in dc tail by referring to theaccompanying drawing illustrating one form which my invention may take,in which Figure l is a perspective view of my im' proved water hammock,the position of the user being indicated in dotted lines;

Fig. 2 is a sectional view on line 22 of Fig. 1;

F i. 3 is a sectional view on' line 3-3 of Fig. a, and

Fig.4: is a sectional view along line H of Fig. 2.

My improved water hammock comprises the cradle or stretcher portion 5which is held taut between two buoyant supports 6 and 7 which arefastened to the opposite eX- tremities of the cradle portion The cradleportion is fastened throughout the greater portion of its width to thebuoyant supports, but a portion thereof is unfastened or preferably cutaway as shown at 7. This accommodates the rounding of the buoyantsupports 6 and 7 when they are blown up without distorting the cradleportion. Straps 8 however maintain the proper alinement of the cradleand its supports. These straps 8 may be made of rigid material, if sodesired, bent to the shape shown in Fig. 1, but they are preferably madeof several plies of canvas stitched together and to the Specification ofLetters Patent.

sides of the cradle and to the ends of the pillows. l Vhen thus madethey are strong enough to cause the cradle and pillows to remain. inalinement. The buoyant supports as shown herein are bags which areadapted to be blown up, thus forming pneumatic chambers. Each of thebags is provided with a valve structure as shown more clearly at 9. Thisvalve structure is shown in detail more particularly in Figs. 2, 3 and4:.

The bag 6, for instance, has an outer flap l0 sewed to it throughout theentire length of this outer flap. A hole 11 is provided through thepneumatic bag 6 under the flap. A month piece 1:2 is fastened to theflap 10 so that air may beblown into the interior of the bag 6. Thepneumatic bags 6 and 7 are made of material which will hold the air asufficient length of time for the purpose desired. Assuming that it isdesired to blow up the bag, then the finger pieces 13 and 14 are graspedto straighten out that portion of the bag through which the hole 11passes, away from the flap 10, whereupon air may be blown in through themouthpiece 12 until the bag is inflated. The presence of the air thenpresses the bag portion tightly against the flap 10 to prevent the airfrom escaping through the hole 11.

From what has been thus described the nature of my invention will bereadily clear to those skilled in the art.

Having thus described means for carrying out my invention, what I claimas new and desire to secure by Letters Patent is:

1. A water hammock comprising a pair of buoyant pillows, a pair of lightstrips connecting the pillows along their side edges, and a yieldablecradle portion supported by the strips to be drawn taut by the expansionof the pillows.

2. A water hammock con'iprising a pair of buoyant pneumatic pillows, alight frame work and cradle connecting the pillows, said frame work andcradle being drawn taut by the expansion of the pillows.

3. A Water hammock comprising a pair of buoyant pneumatic pillows, alight yieldable frame adapted to be turned up at an angle at the endsand supporting the pillows at an incline at each end, and a yieldablecradle portion supported by the frame and pillows.

i. A water hammock comprising a pair of rectangular buoyant pneumaticpillows, a light foldable connecting frame secured to and a yieldtheside ed es of the pillows,

the

able cradle portion supported between connecting frame.

5. A water hammock comprising a pair of buoyant pillows, a Valvestructure for each of said pillows, a pair of strips connecting thepillows along their edges and a yieldable cradle portion supported bysaid strips, the parts being so constructed that the expansion of saidpillows will close the valve structures and draw taut the cradle.

6. A water hammock comprising a pair of buoyant pneumatic pillows, avalve structure for each of said pillows, and a framework and cradleconnecting the pillows, said framework and cradle being drawn taut andsaid Valve being held closed by the expansion' of said pillows.

In witness whereof, I hereunto subscribe my name this fourteenth day ofAugust, A. D. 1917.
